# Configuration file for dnsmasq.

#

# Format is one option per line, legal options are the same

# as the long options legal on the command line. See

# "/usr/sbin/dnsmasq --help" or "man 8 dnsmasq" for details.

# The following two options make you a better netizen, since they

# tell dnsmasq to filter out queries which the public DNS cannot

# answer, and which load the servers (especially the root servers)

# uneccessarily. If you have a dial-on-demand link they also stop

# these requests from bringing up the link uneccessarily.

# Never forward plain names (without a dot or domain part)

#domain-needed

# Never forward addresses in the non-routed address spaces.

#bogus-priv

# Uncomment this to filter useless windows-originated DNS requests

# which can trigger dial-on-demand links needlessly.

# Note that (amongst other things) this blocks all SRV requests,

# so don't use it if you use eg Kerberos, SIP, XMMP or Google-talk.

# This option only affects forwarding, SRV records originating for

# dnsmasq (via srv-host= lines) are not suppressed by it.

#filterwin2k

# Change this line if you want dns to get its upstream servers from

# somewhere other that /etc/resolv.conf

#resolv-file=

# By  default,  dnsmasq  will  send queries to any of the upstream

# servers it knows about and tries to favour servers to are  known

# to  be  up.  Uncommenting this forces dnsmasq to try each query

# with  each  server  strictly  in  the  order  they   appear   in

# /etc/resolv.conf

#strict-order

# If you don't want dnsmasq to read /etc/resolv.conf or any other

# file, getting its servers from this file instead (see below), then

# uncomment this.

#no-resolv

# If you don't want dnsmasq to poll /etc/resolv.conf or other resolv

# files for changes and re-read them then uncomment this.

#no-poll

# Add other name servers here, with domain specs if they are for

# non-public domains.

#server=/localnet/192.168.0.1

# Example of routing PTR queries to nameservers: this will send all

# address->name queries for 192.168.3/24 to nameserver 10.1.2.3

#server=/3.168.192.in-addr.arpa/10.1.2.3

# Add local-only domains here, queries in these domains are answered

# from /etc/hosts or DHCP only.

#local=/localnet/

# Add domains which you want to force to an IP address here.

# The example below send any host in doubleclick.net to a local

# webserver.

#address=/doubleclick.net/127.0.0.1

# --address (and --server) work with IPv6 addresses too.

#address=/www.thekelleys.org.uk/fe80::20d:60ff:fe36:f83

# You can control how dnsmasq talks to a server: this forces

# queries to 10.1.2.3 to be routed via eth1

# --server=10.1.2.3@eth1

# and this sets the source (ie local) address used to talk to

# 10.1.2.3 to 192.168.1.1 port 55 (there must be a interface with that

# IP on the machine, obviously).

# --server=10.1.2.3@192.168.1.1#55

# If you want dnsmasq to change uid and gid to something other

# than the default, edit the following lines.

#user=

#group=

# If you want dnsmasq to listen for DHCP and DNS requests only on

# specified interfaces (and the loopback) give the name of the

# interface (eg eth0) here.

# Repeat the line for more than one interface.

#interface=

# Or you can specify which interface _not_ to listen on

#except-interface=

# Or which to listen on by address (remember to include 127.0.0.1 if

# you use this.)

#listen-address=

# If you want dnsmasq to provide only DNS service on an interface,

# configure it as shown above, and then use the following line to

# disable DHCP on it.

#no-dhcp-interface=

# On systems which support it, dnsmasq binds the wildcard address,

# even when it is listening on only some interfaces. It then discards

# requests that it shouldn't reply to. This has the advantage of

# working even when interfaces come and go and change address. If you

# want dnsmasq to really bind only the interfaces it is listening on,

# uncomment this option. About the only time you may need this is when

# running another nameserver on the same machine.

#bind-interfaces

# If you don't want dnsmasq to read /etc/hosts, uncomment the

# following line.

#no-hosts

# or if you want it to read another file, as well as /etc/hosts, use

# this.

#addn-hosts=/etc/banner_add_hosts

# Set this (and domain: see below) if you want to have a domain

# automatically added to simple names in a hosts-file.

#expand-hosts

# Set the domain for dnsmasq. this is optional, but if it is set, it

# does the following things.

# 1) Allows DHCP hosts to have fully qualified domain names, as long

#     as the domain part matches this setting.

# 2) Sets the "domain" DHCP option thereby potentially setting the

#    domain of all systems configured by DHCP

# 3) Provides the domain part for "expand-hosts"

#domain=thekelleys.org.uk

# Set a different domain for a particular subnet

#domain=wireless.thekelleys.org.uk,192.168.2.0/24

# Same idea, but range rather then subnet

#domain=reserved.thekelleys.org.uk,192.68.3.100,192.168.3.200

# Uncomment this to enable the integrated DHCP server, you need

# to supply the range of addresses available for lease and optionally

# a lease time. If you have more than one network, you will need to

# repeat this for each network on which you want to supply DHCP

# service.

#dhcp-range=192.168.0.50,192.168.0.150,12h

# This is an example of a DHCP range where the netmask is given. This

# is needed for networks we reach the dnsmasq DHCP server via a relay

# agent. If you don't know what a DHCP relay agent is, you probably

# don't need to worry about this.
